Expert Answer
First find the determinant of the given square matrix.
 
That is we need to check whether A is singular (open vertical bar A close vertical bar equals 0) or non-singular (open vertical bar A close vertical bar not equal to 0).
 
If the determinant of the matrix is equal to zero, then the inverse of the matrix does not exist.
 
If the determinant of the matrix is not equal to zero, then the inverse of the matrix exist.
